 DETAILED DESCRIPTION OF THE EMBODIMENTS
FIG. 1 is a side view of an embodiment of an LED bulb 100 having a transparent housing 102, and a base 122. As shown in FIG. 1, multiple printed circuit boards 120 are arranged in a pyramidal structure. Multiple LEDs 120 are attached to the upper surface of the multiple printed circuit boards 120. As illustrated in FIG. 1, there are three printed circuit boards, i.e., a first printed circuit board 106, a second printed circuit board 108, and a third printed circuit board 110. Transparent housing 102 surrounds the printed circuit boards 106, 108, 110 and is attached to base 122. The multiple printed circuit boards 120 are arranged in a pyramidal structure with multiple LEDs 124 attached to the three printed circuit boards 106, 108, 110. However, any number of printed circuit boards may be employed, which is dependent on the number of LEDs used and the total amount of space and volume available to house the multiple printed circuit boards 120.
As illustrated in FIG. 1, a transparent housing 102 surrounds and encloses multiple printed circuit boards 120 that are arranged in a pyramidal structure. Multiple LEDs 124 are conductively connected to the multiple printed circuit boards 120. The first printed circuit board 106 has a first layer of multiple LEDs 116 that are attached to the upper surface of the first printed circuit board 106. The second printed circuit board 108 has a second layer of multiple LEDs 114 attached to the upper surface of the second printed circuit board 108. The third printed circuit board 110 has a top layer of LEDs 112 attached to the top surface of the third printed circuit board 110. The printed circuit boards 106, 108, 110 are electrically connected together by conductors, such as conductor 118. The conductors 118 can also support the printed circuit boards 106, 108, 110 in the pyramidal structure illustrated in FIG. 1 or the printed circuit boards can be held in place in any other desirable manner. The bottom printed circuit board 104 is electrically connected to the first printed circuit board 106. The bottom printed circuit board 104 may contain electrical components, such as a rectifier circuit for rectifying alternating current that is obtained from base 122 for application of a DC potential to the multiple LEDs 124.
The printed circuit boards have a size, shape and vertical spacing so that light from the LEDs 111 is not substantially blocked by other LEDs or the printed circuit boards 106-110, especially in a horizontal and vertically upward direction, as illustrated in FIG. 1. As shown in FIG. 1, third printed circuit board 110 has an outer peripheral edge 126 that does not substantially overlap the second layer of multiple LEDs 114. Similarly, second printed circuit board 108 has a peripheral edge 128 that does not substantially overlap the first layer of multiple LEDs 116. In this manner, a maximum amount of light and heat can be emitted from the multiple LEDs 124 in an outward and upward direction without impinging upon a printed circuit board, such as printed circuit boards 108, 110.
The pyramidal structure illustrated in FIG. 1 facilitates safe and effective heat dissipation while also providing maximum light distribution, because light and heat dissipated from a lower LED layer is not blocked by an upper level printed circuit board. For example, second printed circuit board 108 has a smaller surface area than first printed circuit board 106, and third printed circuit board 110 has a smaller surface area than second printed circuit board 108 and first printed circuit board 106. Therefore, the pyramidal structure helps facilitate safe and efficient heat dissipation, while also providing maximum light distribution. In other words, third printed circuit board 110 does not substantially block light and heat dissipated from second printed circuit board 108, and second printed circuit board 108 does not substantially block light and heat dissipated from first printed circuit board 106.
As shown in FIG. 1, Each printed circuit board has at least one LED soldered to an upper surface. Hence, first printed circuit board 106 provides a first layer of LEDs 116, second printed circuit board 108 provides a second layer of multiple LEDs 114, and a third printed circuit board 110 provides at least one LED as a third layer of LEDs 112. As disclosed below, each layer of LEDs can comprise a single row of LEDs or multiple rows, depending upon the space that is available inside the transparent housing 102. The multiple printed circuit boards 106, 108,110 are connected by conductor 118. A bottom printed circuit board 104 can be employed when additional circuitry is needed or desired, such as resistors, diodes, capacitors, inductors, etc. For example, a rectification circuit can be disposed on bottom printed circuit board 104. A two sided printed circuit board can be used for the first printed circuit board 106, so that bottom printed circuit board 104 can be eliminated.
FIG. 2 is a side view of LED light bulb 200, which illustrates an additional shape of a transparent housing 202 that may be employed. FIG. 2 has a transparent housing 202, and a base 204. Contained within the transparent housing 202 are multiple printed circuit boards 210 arranged in a pyramidal structure, which comprise a first printed circuit board 206, and a second printed circuit board 208, and a third printed circuit board 210. Again, any number of layers can be employed and is dependent upon the number of LEDs used, and the total amount of space and volume available to house the multiple printed circuit board.
The embodiment of the LED light bulb 200 that is illustrated in FIG. 2 is similar and operates in substantially the same manner as the embodiment of the LED light bulb 100, illustrated in FIG. 1. However, the first printed circuit board 206 comprises a double sided printed circuit board, which contains electrical components 212 on the bottom side of the first printed circuit board 206, as shown in FIG. 2. By using a double sided printed circuit board for the first printed circuit board 206, additional space can be saved within the transparent housing 202. Of course, a separate printed circuit board can be used, as illustrated in FIG. 1, for mounting electrical components, as shown in FIG. 1.
FIG. 3 is a top view of the embodiment shown in FIG. 1, showing multiple printed circuit boards 120 in a pyramidal structure. As shown in FIG. 3, the LEDs on each printed circuit board at each different layer 104, 106, 108, 110 do not block light and heat dissipated from the LEDs that are disposed around the periphery of each of the printed circuit boards. The printed circuit boards are stacked in a pyramidal fashion so that the printed circuit board of each higher layer does not substantially block light in a horizontal or vertically upward direction from a lower layer of LEDs. As shown in FIG. 3, the peripheral edge of each printed circuit board does not overlap LEDs of a lower or adjacent layer of LED disposed on the periphery of an adjacent printed circuit board. For example, peripheral edge 126 does not substantially block light and heat dissipated from second layer of LEDs 114 and peripheral edge 128 does not block light and heat dissipated from first layer of LEDs 116. FIG. 3 is used as an illustrative example, and the number of printed circuit boards and LEDs could be increased or decreased depending on the volume and space available to house the desired amount of printed circuit board levels and LED layers.
FIG. 4 is a top view of multiple printed circuit boards 400 arranged in a pyramidal structure having multiple LEDs 410, so that the multiple printed circuit boards are similar in shape. For example, first printed circuit board 402 is rectangular in shape and is beneath second printed circuit board 404, which is also rectangular in shape. The second printed circuit board 404 is smaller in area than first printed circuit board 402. Third printed circuit board 406 has a smaller area than, and is above second printed circuit board 404, which also has a rectangular shape. A fourth printed circuit board 408 has the smallest area of the printed circuit boards 402, 404, 406, and is also rectangular in shape. The rectangular shape of multiple printed circuit boards 400 is shown by way of example and many other various shapes may be employed. For example, multiple printed circuit boards 400 may be shaped in a polygon, curved, oblong, or circular shape, as long as the peripheral edges 412 do not substantially block light and heat dissipated from a lower or adjacent layer of LEDs.
FIG. 5 is a top view of multiple printed circuit boards 500 that are arranged in a pyramidal structure. FIG. 5 illustrates that many printed circuit boards may be employed having various shapes which employ multiple LEDs 510. For example, first printed circuit board 502 has a different shape than second printed circuit board 504. Third printed circuit board 506 has a different shape than second and first printed circuit boards 504, 502. Fourth printed circuit board 508 also has a different shape than the first, second and third printed circuit boards 502, 504, 506. Although the embodiment in FIG. 5 shows printed circuit boards of varying shapes, there is no requirement that the printed circuit boards have varying shapes, but is given as an example of various shapes that could be employed. More importantly, any desired shape can be used, as long as peripheral edges 512 do not substantially block light and heat dissipated from a lower or adjacent layer of LEDs.
The foregoing description of the disclosed embodiments has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the embodiments to the precise form disclosed, and other modifications and variations may be possible in light of the above teachings. The embodiments were chosen and described in order to best explain the principles of the description and its practical application to thereby enable others skilled in the art to best utilize the disclosed description in various embodiments and various modifications, as suited to the particular use contemplated.
